ROOK-CRUSHER.

Application filed February 23, 1910, Serial No. 545,501. Renewed December 29, 1910. Serial No. 600,085.

To all whom 'it' may concern:

Be it known that I, ADoLPH WV. J ONES, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Rock-Crushers, of which the following is a specification.

My invention relates to an apparatus for crushing rock and the like.

It consists in the combination of parts, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a vertical section of my apparatus. Fig. 2 is a horizontal or top View.

It is the object of my invention to provide improvements in that class of crushers in which a crushing member is caused to gyrate within an exterior casing between which and the crushing member the material to be pulverized is caused to pass.

I have here shown my apparatus as in cluding a base 1 having a circular, upwardly divergent shell 9 secured to the top by means of flanges and bolts; a second divergent cast-ing 10 bolted to the casting 9 in the same manner, and a casting 11 bolted to the top of 10, and carrying bearings 11 which serve to support the turnable shaft 18 through which power is applied for the apparatus. This power is applied by means of a pinion 17 fixed upon the shaft 18, and engaging the teeth of a horizontal beveled gear 12. This gear has an eccentrically located guide through which the shaft passes, said shaft having a universal joint bearing at the lower end, and having fixed to it the crushing shoes 5 and 6, between which and the corresponding dies 7 and 8, the material passes for the purpose of crushing. These dies 7 and 8 are supported by and form a lining for the shell 9, within which they are located.

Within the central portion of the base 1 is a vertical circular chamber adapted to receive a casting 2. This casting is capable of vertical adjustment within its chamber, by means of a. screw 19, for a purpose to be hereafter described. The inner portion of the block 2 has a spherical form, and is adapted to receive the ball 3 which fits and is turnable therein.

The lower end of the shaft 4 is fitted as shown into the upper portion of the ball 3, and it will be seen that the gyrations caused by the eccentricity of the shaft connect-ion Specification of Letters Patent.

with the gear 12, will cause the ball to roll within its socket with an easy movement. In order to provide a similar easy movement of the upper end of the shaft 1, this end has its hearing within a globular member 1 1 which fits within the corresponding globular socket 13, and this socket is secured to the horizontal web of the gear 12, by bolts as shown at 13*. These connections of the shaft 4: with the two balls 3 and 14 allow of a free gyratory movement with the least amount of friction. The radius of gyration depends upon the attachment of the socket 13 to the gear 12. I have here shown a series of holes made through the web of the gear 12, and so disposed that by changing the fastening bolts, the throw or eccentricity will be correspondingly changed. The crushing surface consists of the shoes 5 and 6 which act in conjunction with the opposed dies 7 and 8, as previously described.

The lower ends of the shoes 5 have an outward segmental projection as shown at a, and the curvature of these segments, and the corresponding curvature of the bottom of the dies 7, are upon a radius having the center of the ball 3 as their center of arc. Thus the gyratory movement of the shaft 1, carrying with it the shoes 5 and 6, will act to first crush and reduce the larger pieces of ore, which fall between the convergent shoes and dies 6 and 8; then as the material becomes reduced to a greater degree of fineness, it will pass into the space between the concave'and convex surfaces at a, and will be pulverized to a greater degree of fineness, falling thence into the receptacle in the base 1, or it may be delivered through screens, or in any other suitable manner not here shown.

In order to relieve the frictional pressure caused by the gyration of the apparatus, I

have shown a series of rollers or similar antifrictional bearings 15., These rollers are here shown as resting upon a circular plate 16, which is bolted to the'casting 11, and the thrust of the crushing member is received upon these rollers, and between the downwardly projecting flange of the gear 12, and the cast-ing 11.

It will be seen that the shoes and dies, and all wearing parts of the machine may be readily removed and replaced as required, and by the upward adjustment of the block 2, and the parts carried thereby, any wear at the point a may be taken up, and an adjustment made at this point for any desired degree of fineness to which it is desired to crush the material.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. The combination in a gyratory crusher, of exterior dies, and interior coacting shoes, a shaft upon which said shoes are carried, a ball in which the lower end of the shaft is stepped, a globular socket in which said ball is turnable, a corresponding ball and socket support for the upper end of the shaft, a horizontally turnable driving gear to which said ball and socket bearing is eccentrically connected, and means whereby the bearing is adjustable on the gear to vary the radius of gyration of the shaft.

2. In a gyratory crusher, an exterior casing and dies, coacting crushing shoes, an upright shaft upon which said shoes are carried, a ball bearing in which the lower end of the shaft is stepped, a similar bearing through which the upper end of the shaft passes, a horizontally revoluble gear, bolts by which the socket port-ion of the upper bearing is eccentrically secured to the gear, said gear having a series of holes for the bolts whereby the eccentricity of movement of the shaft may be varied.

8. The combination in a gyratory crusher, of downwardly convergent dies, coactiug divergent shoes, a gyratory shaft upon which the shoes are carried, means for varying the radius of gyration of the shaft, a ball and socket support for the lower end of the shaft, segmental, outwardly projecting wings or extensions from the lower shoes, and corresponding concaved ends to the lower coacting dies.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
